English • Make sure that cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress. • Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock, or electrocution. • When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. • An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Place the charger in a position away from any heat source. The charger is ventilated through slots in the top and the bottom of the housing. • Do not operate charger with damaged cord or plug. • Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way. Take it to an authorized service center. • Do not disassemble charger; take it to an authorized service center when service or repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire. • Disconnect the charger from the outlet before attempting any cleaning. This will reduce the risk of electric shock. Removing the battery pack will not reduce this risk. 8

Make sure that cord is located so that it will not be stepped
on, tripped over, or otherwise subjected to damage or
stress.
•
Do not use an extension cord unless it is absolutely
necessary.
Use of improper extension cord could result in risk of
fire, electric shock, or electrocution.
•
When operating a power tool outdoors, use an extension
cord suitable for outdoor use.
Use of a cord suitable for outdoor
use reduces the risk of electric shock.
•
An extension cord must have adequate wire size (AWG
or American Wire Gauge) for safety.
The smaller the gauge
number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. An undersized cord
will cause a drop in line voltage resulting in loss of power and
overheating. When using more than one extension to make up the
total length, be sure each individual extension contains at least the
minimum wire size. The following table shows the correct size to
use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the gauge number,
the heavier the cord.
